Easy to Carry Diagnostic instrument for automobile air-conditioning refrigeration system

car air-conditioning diagnostic instrument

Test and diagnosis items. Basis:

1. Whether the amount of refrigerant in the system is normal;
2. Comparative analysis of refrigerant pressure and temperature;
3. The heat exchange efficiency between the condenser and the evaporator;
4. The analysis of the temperature difference between the inlet temperature of the refrigerant;
5. Whether the expansion valve is dirty and blocked, and whether the opening is normal;
6. Analysis of the degree of sub-cooling of the refrigerant;
7. Whether the drying bottle is dirty or blocked;
8. Analysis of the superheat of the refrigerant;
9. Whether the flow control valve is dirty and blocked, and whether the opening is normal;
10. Comparative analysis of the temperature and pressure of the refrigerant and the temperature of the air outlet;
11. Whether the compressor is worn or not;
12. The comparative analysis of the pressure difference between the high and low pressure of the refrigerant and the temperature of the refrigerant;
13. Whether the system has non-condensable gas;
14. Comparative analysis of high pressure pressure and current ambient temperature;
15. Whether the refrigerated lubricating oil has deteriorated and acidified;
16. The analysis of the water content index of the refrigerated oil;

Product function:

1.It is simple to operate and easy to carry.

2.It provides the detection of high and low pressures of the air conditioning system, the temperature detection of the inlet and outlet of the condenser and the evaporator, the detection of the temperature of the refrigerant, the detection of the degree of supercooling and superheat of the refrigerant, and the detection of the acid content of the refrigerated lubricating oil.

3.This instrument automatically analyzes and judges the operating data of the air-conditioning system according to different ambient temperatures, quickly performs a complete diagnosis of various parameters within a few minutes, and quickly automatically analyzes the test results to provide users with possible failures. Reason analysis report and provide treatment suggestions and solutions.

4.The instrument has its own printing function, and the user can choose to print the latest 10 test results, resulting analysis data, and process the content and data.
